I have a 93 del sol. b16a, for the last week the RPM guage will freeze and the jump all down quickly when i change gears. But not the way it should normally slow down...it will stick and then drop fast..then back up...it's just STICKY acting!! Any suggestions would be really really helpful!!!

 

this can be a component in your dizzy funny enought i cant remeber what part but its the one that sends a signal to your ecu or cluster telling engine spd. it coudl also be something else but you can look here first.
